The NASCAR Xfinity Series in 2025 continues its legacy as the proving ground for future Cup stars, grassroots talent, and a fan-favorite alternative to the top-tier Cup Series. The cars remain visually and mechanically distinct from their Cup counterparts, with an emphasis on driver skill and old-school racing characteristics.

While Cup has moved fully into the Next Gen era, the Xfinity Series preserves a more traditional stock car feel, offering fans a mix of nostalgia and raw excitement. In 2025, the series still uses the composite-bodied "Generation 7" Xfinity cars introduced in the late 2010s, refined over time with minor safety, aerodynamic, and durability updates.
